I have a red devil petrol mower model PDG 4350P How do i control the acceleration or reset the acceleration? It is ticking over slowly after cleaning but though it is smoother I am not sure how to increase the engine speed to overcome the drag of the blade when i start to mow.

although I'm not familier with this machine, most fourstroke engines have a governor, the speed is set by the amount on tension on the governor spring, the more tension the faster it goes. does your machine have a throttle control lever or is it set to operating speed only
